Carollo Validates Aquionics' UV Disinfection System

Aquionics’ InLine+ series of ultraviolet (UV) water disinfection systems are now fully validated in accordance with the U.S. Environmental Protection Agency UV Disinfection Guidance Manual (UVDGM).

According to a June 17 press release, the validation certifies the use of the systems for the Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR) released in November 2006.

The testing was conducted by Carollo Engineers at its Portland, Ore., validation facility and covered a three-dimensional matrix of UV transmittance, flow, and reduction equivalent dose, using both T1 and MS-2 phage test surrogates. Dose delivery equations were derived for all reactors that predict T1 and MS-2 RED as a function of flow, UV-T, UV sensor readings, and microbe UV sensitivity.

“We are proud to be able to offer communities the choice of using our state-of-the-art UV disinfection systems, knowing that they meet the very latest and most stringent drinking water standards," commented Aquionics President Bill Decker.
